Suzhou mechanical vibration sheet metal processing machinery effect of the different products according to different cost considerations and the choice of material, typically cold-rolled plate (SPCC), hot-rolled sheet (of SHCC), galvanized sheet (SECC, SGCC), aluminum (aluminum profile), Stainless steel (mirror, brushed surface, matte).
Sheet metal processing materials selection:
1. The cold-rolled plate SPCC with a material thickness of ≤3.2 mm is selected for electroplating and baking paints, because of its low cost and easy molding. The hot-rolled sheet SHCC, because of its low cost, can also be used for electroplating and paint-painting parts, but it is difficult to form, so it is mainly used for flat parts.
2. Galvanized sheet SECC, SGCC. SECC electrolysis board is divided into N material and P material. N material is not used for surface treatment and the cost is high. P material is used for spraying parts.
3. The conductive material is mainly made of copper, which has a high cost because its surface treatment is nickel plating, chrome plating, or no treatment.
4. Aluminum plate, silver plated, nickel plated. Generally used surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost.
5. Due to the complex cross-section structure of aluminum materials, it is suitable for inserting boxes and surface treatment with aluminum plates.
6. Stainless steel without any surface treatment, but its high cost.
Sheet metal processing precautions:
1. Sheet metal processing facilitates the saving of materials.
2. Reasonably select the gap and edge wrapping method, T=2.0 or less gap 0.2, T=2-3 gap 0.5, and the edge wrapping method uses the long edge packet short edge (doorboard type).
3. Reasonable consideration of tolerances Dimensions: negative difference to go to the end, positive difference to take half; hole size: positive difference go to the end, negative difference to go half.
4. Pay attention to the direction of the glitch.
5. Sections should be drawn drawing, riveting, tearing, bumps (bags), and other position direction.
6. Check material, plate thickness, and plate thickness tolerances.
7. Special angle, inner radius of bending angle (general R=0.5).
8. Similar asymmetry should be highlighted.
9. Zoom in on a larger area.
10. If you need to spray protection place must be clear.
Carbide Taps
OPT Diamond Cutting Tools Co., Ltd are a professional manufacture in producing Cutter Taps ,Thread Forming Taps,pipe taps etc . We offer a complete range of taps in carbide, CPM and HSS-E.For carbide taps, we provied regular stock, and we also provide customization for your designs and logo. It is important to choose a professinonal manufacture to work with you, in order to communicate every details in the design. Our reputation has been built on quality, design and service – all at a competitive price. No matter you are a agent buyer or a factory source for self-use, we will be your most trusted partner.
Carbide taps is used to cut a screw thread in material with a pilot hole, threading is a process of both external and internal machining of threads into a workpiece. A number of angles and measurements defines the thread of the screws and bolts. All are of importance:
The lead is the distance through which a screw advances with one turn in the direction of the shaft. There are single lead threads and multiple lead threads. Multiple lead threads are able to feed faster with fewer revolutions.
The pitch is the distance between the corresponding threads in the axial direction.
The effective diameter is the midway point between the crest and root. In other words, the point where the internal thread and external thread overlap when screws are meshed together. The effective diameter is, along with pitch, one of the most important dimensions in threads.
According to the application, there are several kinds of taps: Machine and hand taps, spiral flute taps, spiral pointed taps, thread forming taps, and Pipe taps and thread milling cutter.
1. Machine and hand taps
The very standard tap, mostly are the Straight flute tap. Typically, tap is constituted by a working portion and a shank portion. The working portion is divided into a cutting portion and a calibration section, the cutting portion having a cutting bevel, responsible for cutting work. The calibration section is used to calibrate the size and the shape of the thread.
2. Spiral flute taps:
The spiral flutes have high cutting performance, eject chips smoothly, leave no chips in the hole bottom, suitable for tapping sticky materials. The chip-hold groove of Spiral fluted tap is spiral. According to the application, they are divided into two kinds: Left spiral flute tap and right spiral flute tap. Left Spiral flute tap tapping the chip to the bottom, suitable for through hole. Right spiral flute tap tapping scraps discharge upwards, so its suitable for blind holes.
3.Spiral pointed taps:
Suitable for through-hole and deep thread, have high strength, long life, fast cutting, dimensional stability, explicit tooth pattern (especially fine tooth). It opens chute in the side of the cutting edge of the straight groove, to form an angle, the chips are discharged forward when threading, suitable for through-hole processing. Relatively large core size design, good strength, can withstand greater cutting force. It is suitable for processing of non-ferrous metals and stainless steel and black metallic.
4. Thread forming taps:
These taps make threads by deforming the materials and do not produce chips. They are suitable for the blind holes of rather soft material or non-ferrous metals. The internally extruded and threaded metal has fibers which are continuous and has high tensile strength and shear strength, and has good surface roughness too.
5. Pipe taps
The pipe taps are used for mechanical joints purpose which is cutting the pipe fitting threads. There are two kinds of types, taps for parallel threads and taps for taper threads. The parallel threads are used for mechanical joints. The taper threads are used for pressure type joints such as water pipes and gas pipes.
6. Thread Milling cutter:
The thread milling cutter is a new developed processing tool in recent years. Its the combination of the milling cutter and the tap, using milling for machining the thread, so we call it the thread milling cutter. It is suitable for processing the large aperture work piece, avoid the disadvantage of high cost for large size Taps.
